#d = 2#

Explanation:

#6 + 3(4d+8) = 54#

Subtract #color(blue)6# from both sides:
#6 + 3(4d+8) quadcolor(blue)(-quad6) = 54 quadcolor(blue)(-quad6)#

#3(4d+8) = 48#

Divide both sides by #color(blue)3: #(3(4d+8))/color(blue)3 = 48/color(blue)3#

#4d + 8 = 16#

Subtract #color(blue)8# from both sides:
#4d + 8 quadcolor(blue)(-quad8) = 16 quadcolor(blue)(-quad8)#

#4d = 8#

Divide both sides by #color(blue)4#:
#(4d)/color(blue)4 = 8/color(blue)4#

Therefore,
#d = 2#

Hope this helps!
